Five storylines: Air Force

Here are five storylines regarding Air Force, Michigan’s opponent on Saturday:

1. Replacing the center: Perhaps more than in any other offense, Air Force’s no-huddle wishbone relies a lot on the play of its center to set all the line calls and make things run smoothly up front. Against Michigan, this will be even more critical considering the size disadvantage. However, the Falcons will be breaking in a new center, Austin Hayes, after starter Michael Husar was lost for the season after tearing the ACL and MCL in his left knee. How quickly Hayes adjusts will be critical to any Air Force success.

2. Running the no-huddle wishbone: Air Force’s best chance for success comes from its old-school, unconventional offense. None of these Michigan players have faced a wishbone team in college and none have seen it at the speed and crispness it can be played. An offense like this, which is led by quarterback Connor Dietz -- coincidentally a senior from Columbus, Ohio -- is predicated on timing and precision. It worked almost flawlessly Saturday as Air Force gained 484 yards rushing.
